were originally
developed to simplify complex
arithmetic calculations.
Logarithms
They were designed to transform
multiplicative processes
into additive ones.
Logarithms
The square roots of negative numbers are called
Imaginary Numbers
a number that can be written in the fform a+bi, where a and bm are real numbers and i = squareroot of -1
Complex numbers
examples of real numbers
1,2,3,4-,1,-2,-3
Examples of imaginary number
4i, -2i
two comple numbers are —- when both their ——- and ——– are equal
Real parts and imaginary parts are equal
Value of i
Squareroot -1
i^2 =
-1
Formula for complex numbers in Addition
(a+c) + (b+d)i
Formula for complex numbers in Subtraction
(a-c) + (b-d)i
Formula for complex numbers in Multiplication
(a+bi) + (a+bi)(di)
